THE SWARM WAS half fledglings now, tiny balloonets that had just cast off their parachuting threads of silk and now struggled bravely to keep up with the great two-meter adult spheres. In the constant chorus of the swarm, the fledglings’ voices were as tiny as their gasbags. Their shrill peepings used the least possible amount of hydrogen, to preserve their precarious lift balance against the few drops in their ballast bladders.
Charlie patrolled majestically through the swarm, driving the bulk of his body reprovingly against a cluster of infant balloonets who were singing against the swarm melody, rotating his eye patches to scan the skies for ha’aye’i, listening to the countersongs of praise and complaint from the other adults of the swarm, and always, always, leading them as they sang. There was much praise, and much complaint. The praise he took for granted. To the complaint he attended with more care, ready either to remedy or rebuke. Three females sang despairingly of little ones who dropped their flying tails too soon, or who could not hold their hydrogen and so drifted helplessly down to the voracious world below. Another pealed a dirge of anger and sorrow, blaming the deformed fledglings on the Persons of the Middle Sun.
This was just; and Charlie led the swarm in a concurrence of sympathy and advice. “Never” — (Never, never, never, sang the chorus) — “never again must we breed near the New Suns.”
The females chorused agreement, but some of the males sang in counterpoint, “But how can we know which is real Heaven-Danger and which is not? And where may we breed at all? The Persons of the Three Suns are under all our air!”
Charlie’s answering song was serene. “I will ask my friend of the Middle Sun. He will know.” (He will know, he will know, chorused the swarm.) But a male sang a dire question. “And when the swarming rapture is on us, will we remember?”
“Yes,” sang Charlie. “We will remember because we must.” (We must, we must.)
That should have settled it. And yet, the song of the swarm was not at peace. Undertones buzzed and discorded against the dominant themes. Even Charlie’s own song faltered how and then, and repeated itself when it should have burst into triumphant new themes. Currents were stirring under the surface of his mind. They never reached consciousness; if they had, no power could have kept him from expressing them in song. But they were there. Worries. Doubts. Puzzles. Who were these Persons of the Three Suns? Where had they come from? They seemed the same, as like as any swarms of balloonists. Yet Charlie’s friend ’Anny ’Alehouse had explained that they were not the same.
First there had been the Persons of the Small Sun. They had seemed no more than another species of devouring Earth-Danger creatures in the beginning, although they had created a tiny sun almost at once. But their camp was almost at the limit of Charlie’s range, and the swarm had not troubled themselves about those Persons.
Then there was the group of Charlie’s friend; and almost at once, the third group, the Persons of the Big Sun. They were worrisome! Their sun was always shining brightly, brighter than the Heaven-Danger at its brightest. Since it was almost the deepest of Charlie’s instincts to swarm in the direction of a bright light, it was actual pain to turn and swim away from the Big Sun. They had almost been trapped when the Persons first arrived — when all three of the parties of Persons of the Suns arrived — because each of them came roaring down through the air on a pillar of Sun-Flame. But none had been close enough to cause them to swarm. By the time the flock had maneuvered near, the flames were gone and the lights were darkened. Then the Persons of the Big Sun had sent one of themselves up into the air in the great queer thing that fluttered and rattled; it was harder than the ha’aye’i Sky-Danger, and even more deadly. Something about it drew balloonists into its swinging claws, and more than a dozen of Charlie’s swarm had been ripped open and gone fluttering down to ground, helpless, despairing, and silent. Now they avoided it in fear and sorrow. Two out of three of the groups of New Persons, and both to be avoided! The one because they killed, the other because they did not fly at all, were no more than any other Ground-Danger, would not have been thought to be Persons at all -
Except for ’Anny ’Alehouse.
Charlie sang of his friend, who redeemed his whole race. ’Anny ’Alehouse and his sometimes companion, ’Appy — they were Persons! They flew as Persons flew, by the majesty and the grace of the air itself. It was a sad thing that even their Middle Sun had flared like a true Heaven-Danger and caused the flock to breed poorly. But it did not occur to Charlie to blame Morrissey’s flare on Dalehouse or Kappelyushnikov; it did not occur to him to think of blame at all. When Kung flared, the balloonists bred. They could not help it. They did not try. They had never developed defenses against a false flare, one lacking in the actinic radiation that helped them make their hydrogen and triggered their fertility. They had never needed any — until now. And they had no way to learn a defense.
The swarm was drifting toward a swelling cumulus cloud; Charlie swelled his singing sac and boomed out, “Hive up, my brothers!” (Hive up, hive up, came the answering chorus.) “Hive up, sisters and mates! Hive up, young and old! Watch for ha’aye’i in the wet shadows! Huddle the little ones close!”
Every member of the swarm was singing full-throatedly now as the swarm compacted, swimming into the ruddy-pink, cottony edges of the cloud. They could see each other only as ghosts, except for the oldest and biggest males, whose luminous markings gave them more visibility. But they could hear the songs, and Charlie and the other senior males patrolled the periphery of the swarm. If ha’aye’i were there, the males could not defend the swarm — could not even defend themselves to any purpose. But they could sing warning, and then the swarm would scatter in all directions, so that only the slowest and weakest would be caught.
Cumulus clouds formed at the top of updrafts of warm air, and the ha’aye’i often sought them out to supplement their comparatively weak lift. There was always a price; what the ha’aye’i gained in speed and control, not to mention claws and jaws, they paid for in smaller lifting bags, so that for them it was always an effort to stay in the air. The ha’aye’i were sharks of the air. They never slept, never stopped moving — and were always hungry.
But this time the swarm was lucky. There were no killer balloons in the cloud, and they emerged intact. Charlie trumpeted out a song of thanksgiving as the flock entered clear air again. All joined.
The swarm was drifting toward the Heat Pole. Charlie rotated his eye patches to catch clues of the movement of the air. He always knew in what direction the winds blew on each level; he was taught by the movement of cloudlets, by the fluttering of dropped fledgling silk, most of all by a lifetime of experience, so that he did not have to think of how to capture a favorable wind; he knew, as surely as any New Yorker hurrying down Fifth Avenue knows the number of the next cross street. He did not want to stray too far from his friend of the Middle Sun, whom he had not seen for some time. He trumpeted for the swarm to rise a hundred meters. The other males took up his song, and from all the gasbags, great and small, drops of water ballast fell. There would be no trouble replacing it for the adults, who were naturally and automatically catching and swallowing the tiny misting of dew during their passage through the clouds. The smaller ones made hard work of it. But they valiantly released swallowed gas into their bags, and the females watchfully butted the littlest ones higher. The swarm stayed together at the new level as its drift changed back in the direction of the camp of the Middle Sun.
No ha’aye’i in sight. Plenty of water on their skins to lick off and swallow, part to hold as ballast, part to dissociate into the oxygen they metabolized and the hydrogen that gave them lift. Charlie was well content. It was good to be a balloonist! He returned to the song of thanksgiving.
They were nearing the edges of their territory, and another swarm bobbed high above them a few kilometers away. Charlie observed them without concern. There was no rivalry between swarms. Sometimes two of them would float side by side for long periods, or even coalesce. Sometimes when two swarms were joined, individuals from one would adhere to another. No one thought anything of that. From that moment they were full members of their new swarm and joined in its songs. But it was more common that each should stay in its own unmarked but known volume of air. They grazed the pollen fields of their own home air without coveting those of their neighbors. Though after half a dozen breedings there might be no single individual still alive of the original swarm, the swarm itself would still drift placidly over the same ten thousand square kilometers of ground. One place was almost like another. Over any one of those square kilometers the sustaining air was always around them. The pollen clouds blew through them all.
Still, some parts of their range were more attractive than others. The mesa where the Persons of the Big Sun had built their shining shells and lit their blazing lamps had been one of their favorites, pollen drifting down off the hills in a pleasant stream, and few ha’aye’i. Charlie sang sorrowfully of his regret as he thought of it, now that they must avoid it for all time to come. The bay of the ocean-lake where ’Anny ’Alehouse lived was, on the contrary, usually to be avoided. The water evaporating from the sea meant columns of rising cloud, and killer balloons no doubt in half the columns. If any member of the swarm had chosen to question Charlie’s decision to return there, it would have been quite reasonable to do so, in practical terms. But in terms of the lives of the balloonists themselves it was quite impossible. Their group decisions were never questioned. If a senior adult sang, “Do thus,” it was done. Charlie was the most senior of adults, and so his song usually prevailed. Not always. Now and then another adult would sing a contrary proposal ten minutes later, but if Charlie returned to his own ten minutes after that, there was no complaint. Each of the other adults loyally picked up his song, and the swarm complied.
There was also the consideration that Charlie had brought to the swarm his friend of the Middle Sun, with his astonishing and fascinating new sounds. This was a Person! Puzzling, yes. But not like those earthbound grubbers of the Small Sun or the strange creatures of the Big Sun who flew only with the help of killing machines. As the swarm drew near the camp of the Middle Sun, all of the adults rotated their bodies so that their tiny faces, like the features of engorged ticks, looked downward, anxious to spy ’Anny or ’Appy. Even the balloonets were caught up in the happy fever of the search; and when the first of the swarm spotted Danny rising to meet them, the song of the flock became triumphant.
How strange ’Anny ’Alehouse looked this time! His lifting sac had always been disagreeably knobby and lacking in any decent coloration, but now it was swollen immensely and knobbier than ever. Charlie might not have recognized him if there had been more than one other like him in all the world to confuse him with. But it was ’Anny all the same. The swarm swallowed hydrogen and dropped to meet him, singing the song of welcome Charlie had invented for his friend.
Dalehouse was almost as overjoyed to see the swarm again as the swarm was to see Dalehouse. It had been a long time! After the storm there had been the time for cleaning up; and before they were through the second ship had dropped out of the tachyon charge state to bring them new people and a whole host of new equipment. That was fine enough, but to make them welcome and to integrate the new things into the old had taken time — more than time. Some of what they had brought had been gifts for the balloonists, and to deliver the gifts meant more load had to be lifted, which meant a bigger cluster of balloons, which meant making and filling new ones and redesigning the ballasting system to compensate. Danny was far from sure it had been worth it.
But there had also been half a kilo of microfiches from the Double-A-L, and those had been worth a lot. Professor D. Dalehouse was now a name to conjure with among xenobiologists. They had quoted his reports in every paper. And the papers themselves had given much to think of. Among the conferees at Michigan State a battle had raged. In the evolution of the balloonists, where was Darwin? When a female scattered her filamentary eggs into the air of Klong like the burst of a milkweed pod and all the males spewed sperm at once, where was the selection of the fittest? What kind of premium on strength, agility, intelligence, or sexual attraction would make each generation somehow infinitesimally more “fit” than the one before in an ontogeny where all the males spurted all their genes into a cloud of mixed female genetic material, with the wind for a mixer and random chance deciding who fathered which on whom? The balloonists kept no Leporello lists. Well any one of them might have fathered a mille-tre; but if so he never knew it.
Charlie could have settled the debate if asked. All the balloonists were sexually mature as soon as they were able to drop their spider-silk parachute threads and float free. But all balloonists were not equal in size.
The older, the bigger. The bigger, the more sperm or eggs they flung into the collective pool. Human beings, by contrast, cease to play a part in evolution before half their lives are over. Wisdom does not come at twenty-five. By the time there is a significant difference between a Da Vinci and a dolt the days of breeding are over. Selection plays no further part. Nor does it in resistance to the degenerative diseases of the old, which is why in two million years the human race has not selected against cancer, arthritis, or arteriosclerosis. Raunchy young cells have been disciplined by the stresses of fifty thousand generations. But past the breeding age the cell runs out of programming. It doesn’t know what to do next.
It begins to fall apart.
With the balloonists it was different. The Charlie-sized giants among them sprayed half a liter of mist-of-sperm into each receptive cloud of eggs, while the tiny first-swarm male balloonets squeezed out hardly a drop. The Charlies had proved their fitness to survive by the most conclusive of tests: they had survived.
Dalehouse was eager to try to settle questions like that as he called to Charlie and swung in to meet him, even more eager to try the new language elements the big computers on Earth had generated for him. What was occupying most of his attention, though, was his gift from Earth. Like the swarm’s greeting song, it was an example of the thing his society did best. It was a weapon.
It was not entirely a free gift, Dalehouse reflected, but then there is nothing without a price. Charlie’s song cost him some of his reserve of lifting gas, as the songs that were their life always cost the swarm. If they sang, they vented gas. If they vented gas, they lost lift. If they lost lift, sooner or later they drifted helplessly down to the eager mouths on the surface and were eaten. Or, almost as bad, had to live on there, helpless and voiceless, until they were able to accumulate and dissociate enough water molecules to recharge their stocks — quickly if Kung was kind enough to flare for them, painfully slowly otherwise. It was a price they paid gladly. To live was to sing; to be quiet was to be dead anyway. But in the end, for most of them, it was the price of their lives.
The price of the gift Danny Dalehouse brought was the lives of the five balloonists who had been sent back to Earth in the return capsule.
The designers at Camp Detrick had made good use of the samples. The two who were dead on arrival were dissected at once. Those were the lucky ones. The other three were studied in vivo. The biggest and strongest of them lasted two weeks.
The Camp Detrick experimenters also had a price to pay, because eight of them came down with the Klongan hives, and one had the severe misfortune to have his skull fill up with antigenic fluid, so that he would never again for the rest of his life stress an experimental subject. Or, indeed, hold a fork by himself. But probably the balloonists who had been his subjects would not have thought that price unfair.
Danny Dalehouse unslung the lightweight carbine from one shoulder and practiced aiming it. Its stock was metal shell, and sintered metal at that; it weighed hardly a kilogram, but half that weight was in high-velocity bullets. It was poor design. He felt sure the recoil would kick him halfway across the sky if he fired it, and anyway, what was the use of high-velocity bullets? What target was there in the Klongan air that needed that sort of impact to destroy it? But the word from Earth brought by the reinforcement party that had been labeled a UN peacekeeping committee was that it must be carried. So he carried it.
He put it back and, somewhat uncomfortably, took Charlie’s gift off the other shoulder. Now, that was more like it. Somebody somewhere had understood what Charlie’s people could do and what they needed in order to protect themselves against predators. It weighed even less than the carbine, and it contained no propellants at all. Its tiny winch could be operated by the claws of a Charlie to tighten a long-lasting elastic cord. Its trigger was sized to fit a balloonist, and what it fired was a cluster of minute needles or, alternatively, a capsule of some sort of fluid. Needles were for airborne predators. The fluid, or so Danny was told, was against creatures like the crabrats, if a balloonist was forced down and needed defense; and it would only incapacitate them without killing.
It would tax all of Dalehouse’s linguistics to convey any part of that to Charlie, but the way to get it done was to begin. He held the crossbow up and sang, carefully attending to the notes he had been taught by the computers at Texas A M. “I have brought you a gift.”
Charlie responded with a burst of song. Dalehouse could understand no more than a few phrases, but clearly it was a message of gratitude and polite inquiry; and anyway, the little tape recorder at his belt was getting it all down for later study.
Danny moved on to the next sentence he had been taught. “You must come with me to find a ha’aye’i. ” That was hard to sing; English does not come with glottal stops, and practicing it for an hour had left Dalehouse’s throat sore. But Charlie seemed to understand, because the song of thanks changed to a thin melody of concern. Danny laughed. “Do not fear,” he sang. “I will be a ha’aye’i to the ha’aye’i. We will destroy them with this gift, and the swarm will no more need to fear.”
Song of confusion, with the words the swarm repeated over and over, not only by Charlie but by all his flock.
The hardest part of all was yet to come. “You must leave the swarm,” sang Dalehouse. “They will be safe. We will return. But now just you and I must fly to seek a ha’aye’i. ”
It took time; but the message ultimately seemed to get across. It was a measure of the balloonist’s trust in his friend from Earth that he was willing to embark on so fearful an adventure with him. The members of the flock never left it by choice. For more than an hour after they had dropped to a lower level and left the flock behind, Charlie’s song was querulous and sad. And no ha’aye’i appeared. They left the Food Bloc camp far behind, drifting down the shore of the sea-lake and then across a neck of it to the vicinity of the Peeps’ tattered colony. For some time Dalehouse had been wondering if the Texas computers had really given him the right words to sing. But then Charlie’s song turned to active fear. They dipped low under a bank of clouds, warm-weather cumuli that looked like female balloonists turned upside down, and from one of them dropped the predatory form of a killer.
Danny was uneasily tempted to slay this first one with his own carbine. It was frightening to see the ha’aye’i stoop toward them. But he wanted to demonstrate his gift to Charlie.
“Watch!” he cried, clumsily grasping the grip that had been designed for balloonist claws. He circled the swelling form of the airshark in the cross-haired sight, designed for balloonist eye patches, feeling the low vibrations of Charlie’s muttered song of terror. At twenty meters he squeezed the trigger.
A dozen tiny metal spikes lashed out at the ha’aye’i, spreading like the cone of fire of a shotgun shell. One was enough. The shark’s bag ripped open with a puff of moisture. The creature screamed once in pain and surprise, and then had no more breath to scream with. It dropped past them, its horrid little face writhing, its claws clutching uselessly toward them, meters away.
A bright trill of surprise from Charlie, and then a roaring paean of triumph. “This is a great good thing, ’Anny ’Alehouse! Will you slay all the ha’aye’i for us?”
“No, not I, Charlie. You will do it for yourself!” And hanging in the air, Danny showed him the clever little crank that worked the elastic cord, the simple breech that the cluster of needles dropped into. For a creature who had never used tools before, Charlie was quick to grasp the operation. Dalehouse had him fire a practice round at a cloud and then watched patiently while the balloonist painfully wound the winch for himself and loaded again.
They were no longer quite alone. Unbidden, the swarm had drifted after them and was floating half a kilometer away, all their eye patches rotated toward them, their distant song sweet and plaintive, like a puppy’s lonely begging to be let in. And down below, the Peeps’ camp was near; Dalehouse could see one or two upturned faces curiously staring at them. Let them look, he thought virtuously; let them see how the Food-Exporting Powers were helping the native races of Klong, if they had so little to do with their time. There were only a handful of them left of the original expedition, and their much-boasted reinforcements showed no signs of arriving.
Reinforcements. Reminded, Dalehouse began the rest of his message for Charlie. “This gift,” he sang, “is yours. But we would ask a gift of you, too.”
“What gift?” sang Charlie politely.
“I do not know words,” sang Danny, “but soon I will show you. My swarm-mates ask you to carry some small things to other places. Some you will drop to the ground. Some you will bring back.” Teaching Charlie how to point the cameras and sound-recording instruments was going to take forever, Dalehouse thought glumly; and how were they ever going to tell him where to drop the clusters of wolftrap sensors and seismic mikes? What seemed so simple on Earth was something else entirely on Klong -
“Beware, beware!” sang the distant, frantic voices of the swarm.
Tardily Danny looked around. The ha’aye’i’s rush caught them unaware. It came from behind and below, where Dalehouse had not thought to look. And Charlie, fondling his new toy and trying to understand what Dalehouse wanted of him, had been careless.
If it had not been for the distant shrieking of the swarm, the creature might have had them both. But Charlie spun faster than Dalehouse, and before Danny could unlimber his carbine the balloonist had shown how well he had learned his lesson by killing the killer. Either of them could have reached out and caught the long, wicked claws of the ha’aye’i as it fell past them; it was that close.
“Well done!” yelled Dalehouse, and Charlie pealed in rapture:
“Well, well done! How great a gift!” They rose to rejoin the swarm -
Lances of golden fire reached up faintly toward the flock from the Peeps’ camp below.
“My God!” shouted Danny. “The fools are setting off fireworks!”
The rockets exploded into showers of sparks, and all through the swarm balloonists were bursting into bright hydrogen flame.
